After a couple of requests I decided to post this. Attached is my whole
kickstart file. Below are the sections that automatically configure the
disks.
The drives are configured like so:
100MB /boot on first disk
1GB / on first disk
1GB /tmp on first disk
($drive_size / 15) /usr on first disk
($drive_size / 15) /var on first disk
Recommended swap size on first disk
Anything left on first disk is configured as /home
If there is a second disk, partition the whole thing as /backup
If there is a scsi disk (/dev/sda exists):
- use it as the first drive
- if a second scsi disk exists use it as the second drive (/dev/sdb)
- or if an ide disk exists, use it as the second drive
If there are no scsi disks (/dev/sda is absent):
- use /dev/hda as first drive
- if /dev/hdb exists, use it as the second drive
It is a somwhat static configuration, however this is our standard
configuration for machines and it can be easily changed when needed.
The script can't be 100% flexible without user intervention.
Email me with any questions.
